You might as well answer SCJP 6.0 in that case..There is very little difference between 5.0 and 6.0...Only few minor changes..So prepare for SCJP 5.0 and learn those few extra things..I'm also planning to do the same.
Thanks everyone for your input. I'll keep my fingers crossed that they keep it open for another 2 months.
I would like to take the 6.0 test, but I am not sure I'll have the time to prepare for it... I am working in a very narrow time window before school restarts in August. But thanks for the recommendation.
